we have an unix system which has
load average normally about 20.
but while i am running a particular unix batch which performs heavy
operations on filesystem and database average load
reduces to 15.
how can we explain this situation?
while running that batch idle cpu time is about %60-65... (0 Replies)
Hello all, I have a question about load averages.
I've read the man pages for the uptime and w command for two or three different flavors of Unix (Red Hat, Tru64, Solaris). All of them agree that in the output of the 2 aforementioned commands, you are given the load average for the box, but... (3 Replies)
Hello, Here is the output of top command. My understanding here is,
the load average 0.03 in last 1 min, 0.02 is in last 5 min, 0.00 is in last 15 min.
By seeing this load average, When can we say that, the system load averge is too high?
When can we say that, load average is medium/low??... (8 Replies)
Hi,
i have installed solaris 10 on t-5120 sparc enterprise.
I am little surprised to see load average of 2 or around on this OS.
when checked with ps command following process is using highest CPU. looks like it is running for long time and does not want to stop, but I do not know... (5 Replies)
Hello AlL,..
I want from experts to help me as my load average is increased and i dont know where is the problem !!
this is my top result :

Hi ,
I am using 48 CPU sunOS server at my work.
The application has facility to check the current load average before starting a new process to control the load.
Right now it is configured as 48. So it does mean that each CPU can take maximum one proces and no processe is waiting.

Hi,
I am getting a high load average, around 7, once an hour. It last for about 4 minutes and makes things fairly unusable for this time.
How do I find out what is using this. Looking at top the only thing running at the time is md5sum.
I have looked at the crontab and there is nothing... (10 Replies)

IDA(4) BSD Kernel Interfaces Manual IDA(4)NAME
ida -- Compaq Intelligent Drive Array Controllers
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device scbus
device ida
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
ida_load="YES"
DESCRIPTION
The Compaq Intelligent Drive Array (IDA) technology is used to distribute data across an array of hard drives. It unites these hard drives
into one or more high-performance logical drives. The drive array is managed by an array controller.
These controllers have the ability to provide fault tolerance for the connected drives and optionally provide write cache for the logical
drives. It is also possible for an application to access the SCSI bus subsystem directly by using the pass-through interface.
HARDWARE
The following controllers are supported by the ida driver:
o Compaq SMART Array 221
o Compaq Integrated SMART Array Controller
o Compaq SMART Array 4200
o Compaq SMART Array 4250ES
o Compaq SMART 3200 Controller
o Compaq SMART 3100ES Controller
o Compaq SMART-2/DH Controller
o Compaq SMART-2/SL Controller
o Compaq SMART-2/P Controller
o Compaq SMART-2/E Controller
o Compaq SMART Controller
IMPLEMENTATION NOTES
Extreme caution should be exercised when using the pass-through interface. It is possible to interfere with normal system I/O and cause
hangs if pass-through is used to an active device. Pass-through should only be used to a device that is otherwise quiescent.
